LINNEUS OHEETHAM, OF LEWISTON, MAINE.

Specification forming part of Letters Patent No. 120,037, dated October17, 1871.

To all whom it may concern:

Be it known that I, LINNEUS CHEETHAM, of Lewiston, in the county ofAndroscoggin and State of Maine, have invented a new and ImprovedScavenger-Roll for Spinning-Machines;-

and I do hereby declare that the following is a full and exactdescription of the same, reference being had to the accompanying drawingand to the letters of reference marked thereon.

This invention has for its object the production of a scavenger-roll forspinning-machines which shall be cheaper in its construction and moredurable than the ordinary roll and consists broadly in providing theroll with grooves, in which are placed woolen cords or theirequivalents, as will be fully described hereinafter.

In the drawing, Figure 1 represents a front elevation; Fig. 2, a sideelevation of a frame having my improved roll; and Fig. 3, a section ofthe roll detached.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe in detail its construction.

A represents the scavengerroll, preferably made of wood, which isprovided with the grooves a, preferably arranged spirally about theroll, as shown. In each groove is laid a woolen cord, b, held in anyproper manner, but preferably secured by means of pegs driven into holesat the ends, as shown in Fig. 2. The position of the roll relatively tothe other parts of the spinningframe and its mode of operation are thesame as those of the ordinary roll, and they need not, therefore, beparticularly described here.

The advantages of this construction are as follows: The cotton thataccumulates upon the scavenger-roll must often be cleared away by meansof a knife, and when constructed in the ordinary manner this operationsoon renders the roll unfit for use. cotton may be cut away by using theknife between the grooves without injury to the woolen cord, and even ifthe latter is cut away at any time it may be replaced at a triflingcost, while replacing the cloth in the old form of roll is a matter ofconsiderable expense.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

A scavenger-roll provided with grooves filled with woolen cord or itsequivalent, as described.

This specification signed and witnessed this 7th day of August, 1871.

With my improved roll, however, the
